protected com.gemstone.gemfire.cache.Region	getRandomRootRegion() Selects and returns a random rootRegion
static void	HydraCloseTask_validateKeysInRegion() This validation task does not do any coordination between the publishing, recyclePrimary and validation.

static void	HydraTask_initializeBridgeClient() Setup DynamicRegionFactory and create non-dynamic parent regions
static void	HydraTask_initializeBridgeServer()
static void	HydraTask_putSequentialKeys() Performs ITERATIONS puts on a unique entry in TestRegion Each assignment of this task gets a new key from the NameFactory, and then updates that key with sequential values from 1 -> ITERATIONS.
static void	HydraTask_recyclePrimary() Recycle primary gateway in WAN Site #1 (to force redundancy recovery)
static void	HydraTask_startGatewayHubTask() Add Gateways and start the GatewayHub Note: This must be done after all servers have been initialized (and invoked createGatewayHub(), so the hydra WAN blackboard knows about all the available servers and endpoints.
protected void	initializeBridgeClient()
protected void	initializeBridgeServer()
protected void	putSequentialKeys()
protected void	recyclePrimary()
static void	startAndConnectLocatorTask() Connects a locator to its distributed system.
protected void	startGatewayHub(String gatewayConfig) Starts a gateway hub in a VM that previously created one, after creating gateways.
static void	stopLocatorTask() Stops a locator.
protected void	validateKeysInRegion()
protected void	validateRegion(com.gemstone.gemfire.cache.Region aRegion, boolean verifyModVal)
protected void	validateSequentialKeys() This validation method coordinates client operations/validation with recyclePrimary Called directly from putSequentialKeys task which coordinates publishing, recyclePrimary and validation by pausing and waiting for activities to sync up.

Constructor Detail

WANRecoveryTest

public WANRecoveryTest()

Method Detail

createLocatorTask

public static void createLocatorTask()

Creates a (disconnected) locator.

startAndConnectLocatorTask

public static void startAndConnectLocatorTask()

Connects a locator to its distributed system.

stopLocatorTask

public static void stopLocatorTask()

Stops a locator.

HydraTask_initializeBridgeServer

public static void HydraTask_initializeBridgeServer()

initializeBridgeServer

protected void initializeBridgeServer()

HydraTask_startGatewayHubTask

public static void HydraTask_startGatewayHubTask()

Add Gateways and start the GatewayHub Note: This must be done after all servers have been initialized (and invoked createGatewayHub(), so the hydra WAN blackboard knows about all the available servers and endpoints.

startGatewayHub

protected void startGatewayHub(String gatewayConfig)

Starts a gateway hub in a VM that previously created one, after creating gateways.

HydraTask_initializeBridgeClient

public static void HydraTask_initializeBridgeClient()

Setup DynamicRegionFactory and create non-dynamic parent regions

initializeBridgeClient

protected void initializeBridgeClient()

createGatewayHub

protected void createGatewayHub()

HydraTask_recyclePrimary

public static void HydraTask_recyclePrimary()

Recycle primary gateway in WAN Site #1 (to force redundancy recovery)

recyclePrimary

protected void recyclePrimary()

HydraTask_putSequentialKeys

public static void HydraTask_putSequentialKeys()

Performs ITERATIONS puts on a unique entry in TestRegion Each assignment of this task gets a new key from the NameFactory, and then updates that key with sequential values from 1 -> ITERATIONS. This allows the client listeners to verify incremental updates on the key and for a final CLOSETASK validator to verify that all clients have all keys with the correct ending value (ITERATIONS).

putSequentialKeys

protected void putSequentialKeys()

HydraTask_doEntryOperations

public static void HydraTask_doEntryOperations()

Performs puts/gets on entries in TestRegion

doEntryOperations

protected void doEntryOperations()

closeCacheAndDisconnectFromDS

public static void closeCacheAndDisconnectFromDS()

Close the cache (and disconnect from the DS) This should prevent the ShutdownException: no down protocol available! during Shutdown (if locators (client vms) are shut down prior to application client vms

validateSequentialKeys

protected void validateSequentialKeys()

This validation method coordinates client operations/validation with recyclePrimary Called directly from putSequentialKeys task which coordinates publishing, recyclePrimary and validation by pausing and waiting for activities to sync up. Use validateKeysInRegion for concurrent (non-pausing) tests which use doEntryOperations() on randomKeys vs. putSequentialKeys/Values.

HydraCloseTask_validateKeysInRegion

public static void HydraCloseTask_validateKeysInRegion()

This validation task does not do any coordination between the publishing, recyclePrimary and validation. It should be used as a one time call at the end of the test (as a CLOSETASK). Verifies the region has the same keySet as the server region and that ValueHolder.myValue is correct for each key. concurrent (non-pausing) tests should use HydraCloseTask_validateKeysInRegion().

validateKeysInRegion

protected void validateKeysInRegion()

validateRegion

protected void validateRegion(com.gemstone.gemfire.cache.Region aRegion,
                              boolean verifyModVal)

getRandomRegion

protected com.gemstone.gemfire.cache.Region getRandomRegion(boolean allowRootRegion)

Selects random region (copied from dynamicReg/DynamicRegionTest.java)

createDynamicRegion

protected com.gemstone.gemfire.cache.Region createDynamicRegion(String parentName,
                                                                String drName)

Creates a dynamic region (from dynamicReg/DynamicRegionTest.java)

getRandomRootRegion

protected com.gemstone.gemfire.cache.Region getRandomRootRegion()

Selects and returns a random rootRegion

HydraEndTask_verifyConflation

public static void HydraEndTask_verifyConflation()

verifyConflation

protected void verifyConflation()

getConflatedEventCount

protected double getConflatedEventCount()
